1990 suspra sunsport-what to inspect/check first

I have just recently purchased 1990 supra sunsport classic.
The motor starts and runs. Sounds ok but likes to start with choke on at first...Although, I dont trust anybody when it comes to boat motors. I like to do the maintenance and service myself if I can. This boat comes with a 454 PCM motor with about 850hrs on it and my questions are as follows

1) what problems should I be most concerned with this motor?
2) maintenance recommendations? Ie: known issues with specific part wear.
3) best place to find parts for the motor.

I can tell I will have a long relationship with this boat assuming everything in the motor checks out and I look foreward to keeping the forum updated with how it goes. I'll be posting pics of before and after once I get it all cleaned up
Thanks in advance

Congrats on the purchase. New members can’t post pics until they have a few more posts to prevent spam. Posting pics here sucks bigly so use a third party website like Imgur.com or use the Tapatalk app.

1. I think not winterizing the motor correctly is the number one issue people experience with inboard boats. Search for a good thread on here or YouTube to learn more.

2. Change the oil and the impeller regularly.

3. Visit SkiDim.com Calling them works best, have great tech support.

Awesome thanks for the heads up! I've been trying to research YouTube university trying to find exactly how to replace the impeller (I'm not having any luck) since I cant view pics in here it's hard to see the photos of what other ppl are doing for a fake lake and impeller change...

Anyone have a part# for the impeller kit for the 454 pcm engine? Engine code is PLM-WR-L10

Highly reccomend a silicon impeller. Pretty sure my backup rubber one will dryrot before the silicon one will give up.

Also, when I was removing, one of the bolts snapped on the sherwood pump. It didnt take much to snap, I dont think its seized it's probably just a severely corroded/rusted bolt. Will try to remove later today at work. https://uploads.tapatalk-cdn.com/202...88338ef1f4.jpg
